Two-component cosmetic

Abstract

The purpose of the present invention is to provide a two-component cosmetic which, when a first formulation and a second formulation are sequentially applied, forms a uniform gel film on the skin while imparting a feeling of moisture permeating the skin, thereby providing an ideal skin feel. The present invention pertains to a two-component cosmetic containing: (1) a first formulation containing a gel formation-promoting substance; and (2) a second formulation containing a gel-forming substance. The two-component cosmetic is characterized in that the first formulation is applied to the skin, and then the second formulation is applied thereto.

The invention claimed is: 
     
       1. A method for providing human skin with a barrier having an occlusive effect on moisture evaporation, comprising the ordered steps of:
 (1) applying to the skin a first component, which comprises a first substance consisting of a metal ion selected from the group consisting of Na + , K + , Ca 2+ , Mg 2+  and Al 3+ ; and 
 (2) applying to the skin, over the first component, a second component, which comprises a second substance consisting of a water-soluble polymer selected from the group consisting of soluble alginate and gellan gum; 
 
       whereby a barrier having an occlusive effect on moisture evaporation is formed on the skin. 
     
     
       2. The method of  claim 1 , wherein: the first substance is Ca 2+  or Mg 2+ , and the second substance is a soluble alginate. 
     
     
       3. The method of  claim 1 , wherein: the first substance is Ca 2+  or Mg 2+ , and the second substance is gellan gum.
